What impact does alcohol have on the ability to perform motor tasks?

Alcohol has a significant impact on the ability to perform motor tasks, and the correct answer highlights that it disrupts this ability. When a person consumes alcohol, it affects both the central nervous system and coordination. This impairment can lead to slower reaction times, decreased motor skills, and impaired judgment, making it challenging to perform tasks that require precise control and timing, such as driving.

The effects of alcohol include diminished balance, reduced hand-eye coordination, and overall diminished physical performance. This is particularly critical when considering activities like operating a vehicle, where motor skills and quick reflexes are essential for safety.

In contrast, the other options do not accurately reflect the effects of alcohol on motor tasks. Claiming that alcohol improves motor ability ignores the scientific consensus and research findings that demonstrate performance degradation with alcohol consumption. Stating that alcohol has no effect overlooks the extensive evidence showing its detrimental influence. Lastly, the idea that alcohol only affects mental tasks fails to recognize that physical skills, which involve motor functions, are also compromised under the influence of alcohol.
